Dell Ambient Thermistor - What is that?

Hi Maryws07,

Thermistors are ceramic components whose electrical resistance rapidly increases when a certain temperature is exceeded. This feature makes them ideal for use in countless applications of modern electrical and electronic engineering.

Ambient Thermistor temperature is the temperature with in the laptop. 

Okay,thank you. I'm asking because my laptop has an idle temperature of 55-60 degrees and i think it's a bit high. Full load is 85-88 degrees.

Hi Maryws07,

The alarming temperature of the laptop in operating environment is 75º to 85º C. If the laptop fans are not spinning then use this link for troubleshooting the fans and air vents: http://dell.to/L49lxh

Please reply for further help.

The fan kicks in two steps,so it works fine.

But i'm worried about my temperatures,other laptops have lower idling temperatures.Mine idles at 55 degrees. So i find it a bit strange

Hi Maryws07,

I would suggest you to update the latest BIOS for the system. To update the BIOS please follow the below mentioned steps:

1. Visit the following website:  http://dell.to/YFr4GW
2. Enter the Service tag of the computer in the box provided and click “Submit”.
3. In the next page, click drop down arrow to select the Operating System which is installed in the computer.
4. Under category BIOS, click “Get driver” and save the file on desktop.
5. Ensure to connect the AC Adapter to the computer and the battery level is more than 15% to run the BIOS file.
6. Follow the on-screen instructions to update the BIOS.
7. Restart the computer when prompted.

Check the functionality of the system temperature and reply.

Just did a bios update and the idle temperature is still about 55 degrees. My room is kind of warm,i'll have to find a thermometer and find out for sure. But it really bugs me,i have an old MSI EX720 with A C2D T5800 and the idle temperature it's the same as my Brand New Dell 17R SE. That ain't right....

Hi Maryws07,

I would suggest you to check if there are any obstructions in the Air vents, use this link for troubleshooting the fans and air vents: http://dell.to/L49lxh

Please reply for any further help.

I don't think the vents are the problem,as i said, the laptop is brand new. The strange part is that the Video cards stays at maximum 45  -  50 degrees,while the CPU is at 55 - 58.

Also,in Everest Ultimate Edition, my Computer freezes for 1 second every few seconds when Everest changes temperature readings...i don't think it's related but...worth mentioning.

I was in everest and my computer was at 53 degrees and i pressed Stress Test. After 1 second the Temperature jumped to 68 degrees. Kind of a big jump for 1 second... maybe defective sensor ?

Also a jump from 57 degees to 76 degrees after 1-2 seconds of stress test.

Meanwhile my MSI EX720 runs a stress test for 10 minutes with a maximum temperature of 68. Even the fan didn't kick in to a higher speed... This really bums me out,cause i just paid 1100 euros for this laptop...

Hi Maryws07,

In some scenarios charging the battery for a long time can also increase the temperature of the laptop.

Please try disconnecting the battery and restart the computer by connecting only the AC adapter.

Check the temperature of the laptop now, and reply.

I tried without the battery. No dice. Still idling at 55-58 degrees.

I left this morning and left my laptop on,when i came back 4 hours later the laptop was in sleep mode i believe,the power led was blinking.

I turned it on and it was idling at 40~,ran a 10 minute stress test and the temperature was maximum 76 degrees.Stopped the test and the idling went to 46-47. But now it's 55-58 again.

I'm really getting tired of this laptop,Something is wrong with it...

I don't care if it shows the wrong temperature,but i need to know that is the issue and not something wrong with the processor,motherboard,or cooling system.

Oh,and everest is showing a 7% wear level on my battery....I have this laptop since January first...never used it on battery

I just installed speedfan and my core 1 idles at 50 and core 3 at 60.

Sometimes is 45 core 1 and 55 core 3. 10 degrees difference between cores.

So my hard disk appears to reach 58 degrees in Assassin's Creed...Should i send this back to warranty?

Hi Maryws07,

I can understand electronic devices can create confusion and frustration when they do not work the way they are designed for.

I would like you to run custom test on fans before coming to a conclusion.

To run custom test please follow the below mentioned steps:

1. Switch on the computer, tap F12 at dell logo to enter “One-time boot menu”.
2. Use the up/down arrow keys to highlight “Diagnostics” and press enter.
3. Select Custom Test and select System fans.
4. If the test fails, please capture the error code and let me know for the next course of action.

If the test passes, please check the temperature in safe mode with networking,

To Check in Safe Mode, please follow the below mentioned steps:

1. Restart the computer.
2. Keep tapping F8 on the Dell Logo Screen.
3. Once the computer enters Advanced Boot Option, select Safe Mode with networking using the up/down arrows and Press Enter.

Check the temperature and post the results.
